Open and Close a Form

[Paul]

Hi,
I created a Logon Form that gives the User Two command
buttons to choose from:
(1) transplant Coordinator
(2) Clinicial Coordinator

Once a user selects the desired option, I want to close
this form.
This Code Opens Option (1) and I need to add code to close
the Logon form.
Private Sub Command0_Click()
Dim stDocName As String
Dim stLinkCriteria As String
stDocName = "Main"
DoCmd.OpenForm stDocName, , , stLinkCriteria
End Sub
